Description

Technical Field

[0001] The present invention relates to the technical field of data visualization display, and specifically to a big data and visualization three-dimensional display system for national land space master planning. Background Art

[0002] Big data technology is developing rapidly. From an industry perspective, smart businesses such as smart cities are developing rapidly in the current market. Currently, big data products are relatively mature and are widely used in Internet management departments, military forces, enterprises and universities; in addition, there are also fields such as business intelligence and industrial monitoring.

[0003] According to the patent application number CN202111195458.3, the patent includes: a general visualization tool module for providing general components of editable configuration items according to different user needs, and building a visualization page according to the configuration items of the general components; a data parsing module for obtaining data chart information from different interfaces, and performing compatibility processing on the data chart information so that different data charts can be displayed on the visualization page; a 3D map processing module for obtaining a building layer from a map interface, performing a cyclic parsing of the building layer, obtaining and processing the building outline data, removing useless data or overlapping data in the building outline data, generating a 3D map layer file, and displaying a new 3D map on the visualization page.

[0004] The system of the above patent is versatile and highly extensible, and is convenient for users to customize according to actual conditions, making the big data display more personalized and suitable for a variety of application scenarios, reducing the development cost of big data visualization display. However, since the data will have different degrees of display effects when displayed, if a single display effect is presented, it will cause a waste of resources. The above patent does not conduct a good adjustment analysis based on the actual situation. Summary of the invention

[0005] In view of the shortcomings of the existing technology, the present invention provides a big data and visual three-dimensional display system of the national land space master plan, which solves the problem of a single display method and the failure to reasonably adjust and analyze the display effect based on actual conditions.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a big data and visual three-dimensional display system for the overall planning of national land space, including: The intelligent information acquisition terminal is used to display the basic information corresponding to the three-dimensional data, including the display location, display time and display clarity, and transmit the basic information to the display situation analysis terminal. The display location indicates that the national land space master plan big data is displayed at the corresponding location, such as a hall, elevator room or a shopping mall, and the display time indicates the playback time of the national land space master plan. The playback time is expressed by loop playback, specifically the time interval between single loop playbacks.

[0007] The display situation analysis terminal is used to obtain the transmitted display location and display time information, and analyze the personnel corresponding to the display location. By classifying the personnel coming and going into concerned personnel and non-concerned personnel, and judging whether the display clarity needs to be adjusted according to the number of the two, judgment information is generated at the same time. The judgment information includes the result of needing adjustment and the result of not needing adjustment. The specific method of generating the judgment information is as follows: S1: Obtain different display screens in the display location, and label them as i, where i=1, 2, ..., j, then obtain the display areas corresponding to different display screens as Qi, and mark the overlapping display intervals of adjacent display screens as overlapping areas; specifically, relative to an exhibition hall, there will be different display screens inside the exhibition hall, and the contents played on the display screens will also be different, and the display areas for different display screens will also be different.

[0008] S2: Then, the target display screen and its adjacent display screens are obtained, and the target display area, non-target display area and overlap area are obtained. Then, the video surveillance is obtained and its content is identified. According to the content, the number of people corresponding to the display location is obtained, recorded as R, and the number of people corresponding to the target display area, non-target display area and overlap area are obtained, recorded as Rm, Rn and Rc respectively; S3: Obtain the number of people Rc in the overlapped area and obtain the video surveillance in the overlapped area, then analyze and judge the people in the overlapped area according to the video surveillance, and classify them into persons of interest and persons of no interest, and the specific analysis method is as follows: S31: Collecting the information of the person in the video surveillance, establishing a rectangular coordinate system with the person's shoulder as the horizontal coordinate and the head as the vertical coordinate, and then analyzing the person's head movement; S32: When there is a horizontal rotation angle between the person's head and the rectangular coordinate system, determine the direction corresponding to the head. If the direction corresponding to the head is the target display area, then determine whether there is an up-down rotation angle of the head. If so, it means that the person's visual range matches the target display area, and the person is marked as a person of interest. If not, the person is marked as a non-person of interest. If the rotation direction corresponding to the head is not the target display area, the person is marked as a non-person of interest. S4: Obtain all concerned persons and non-concerned persons, and obtain their corresponding numbers as R1 and R2, and compare the two. When R1≥R2, it means that the number of concerned persons exceeds the number of non-concerned persons, and an adjustment result is generated. On the contrary, when R1<R2, it means that the number of concerned persons does not exceed the number of non-concerned persons, and a result that does not require adjustment is generated. Specifically, by comparing the number of concerned persons and non-concerned persons in the exhibition hall, it is determined whether the target display screen needs to be adjusted accordingly.

[0009] The information adjustment display terminal is used to obtain the transmitted judgment information and analyze the generated adjustment results. By analyzing the current clarity of the target display screen and paying comprehensive attention to the changes in the number of people, reasonable adjustments are made and adjustment information is generated. At the same time, the adjustment information is transmitted to the adjustment information output terminal. The specific method of generating the adjustment information is as follows: P1: Obtain the clarity adjustment standard and the current clarity transmitted by the real-time data acquisition terminal, and then obtain the changes in the number of people being followed within the time period t. When the number of people being followed increases, the increase in the time period t is calculated and recorded as Z. When the number of people being followed decreases, the decrease in the cycle time t is calculated as X. Specifically, the current clarity defaults to high-definition playback.

[0010] P2: Then the increase amount Z and the decrease amount X are obtained, and the two are analyzed to generate corresponding adjustment information, and the specific analysis method is: The specific method for analyzing the increase Z is: Get the current clarity and determine whether it can be further increased. If it cannot be further increased, no processing is performed and the current clarity is maintained. If it can be further increased, substitute the increase Z and the number of people R within the cycle time t into the formula The adjustment value Q is calculated, and then the adjustment value Q is matched with the preset value Qy to determine whether the adjustment value Q is within the specific adjustment interval, and the adjustment information is generated according to the matching result.

[0011] The specific method of analyzing the reduction amount X is similar to the method of analyzing the increase amount, and the adjustment information is generated according to the matching results.

[0012] P3: Then, the real-time data transmitted by the real-time data acquisition terminal is obtained, and secondary adjustment analysis is performed on the adjusted target display screen according to the real-time data, and secondary adjustment information is generated at the same time. The specific generation method is as follows: The change of the concerned persons within the time period t1 is obtained. If the number of concerned persons increases, the clarity is not adjusted and normal information is generated. On the contrary, if the number of concerned persons decreases, the change of the concerned persons within the unit time is calculated and recorded as Rb, and compared with the preset value Ry. If Rb≥Ry, it means that the decrease in the number of concerned persons exceeds the preset value and the decrease adjustment information is generated. On the contrary, if Rb<Ry, it means that the decrease in the number of concerned persons does not exceed the preset value and normal information is generated. Specifically, the specific definition of the unit time is based on the actual situation and can be one hour, half an hour or two hours. The specific value is determined by the operator, and the preset value Ry is also set by the operator.

[0013] The adjustment information output terminal is used to obtain the transmitted adjustment information and secondary adjustment information, and display it to the operator through a display device.

[0014] Beneficial Effects The present invention provides a big data and visual three-dimensional display system for the overall planning of national land space. Compared with the prior art, it has the following beneficial effects: The present invention adjusts the display effect corresponding to the current display screen according to the number of people in the exhibition hall, and classifies the exhibition hall personnel into concerned personnel and non-concerned personnel, and further determines whether adjustment is needed according to the change in the number of concerned personnel, and makes specific adjustments according to the specific number change value. By adjusting the display effect in an adjustable manner, the overall resource consumption can be reduced when the number of people is small, thereby achieving the purpose of energy saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 is a system block diagram of the present invention; Figure 2 This is a schematic diagram of the exhibition area of ​​the present invention. DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1 and Figure 2 This application provides a big data and visual three-dimensional display system for the overall national land space plan, including: an intelligent information acquisition terminal, a display situation analysis terminal, an information display adjustment terminal, a real-time data acquisition terminal and an adjustment information output terminal.

[0018] The intelligent information acquisition terminal is used to display the basic information corresponding to the three-dimensional data, including the display location, display time and display clarity, and transmit the basic information to the display situation analysis terminal. The display location indicates that the national land space master plan big data is displayed at the corresponding location, such as a hall, elevator room or a shopping mall, and the display time indicates the playback time of the national land space master plan. The playback time is expressed by loop playback, specifically the time interval between single loop playbacks.

[0019] The display situation analysis terminal is used to obtain the transmitted display location and display time information, and analyze the personnel corresponding to the display location. By classifying the personnel coming and going into concerned personnel and non-concerned personnel, and judging whether the display clarity needs to be adjusted according to the number of the two, judgment information is generated at the same time. The judgment information includes the result of needing adjustment and the result of not needing adjustment. The specific method of generating the judgment information is as follows: S1: Obtain different display screens in the display location, and label them as i, where i=1, 2, ..., j, then obtain the display areas corresponding to different display screens as Qi, and mark the overlapping display intervals of adjacent display screens as overlapping areas; specifically, relative to an exhibition hall, there will be different display screens inside the exhibition hall, and the contents played on the display screens will also be different, and the display areas for different display screens will also be different.

[0020] Combined with actual analysis, as shown in the attached Figure 2 As shown, there are two display screens, namely the first display screen and the second display screen, and the two display screens correspond to two display areas, namely the first display area and the second display area. The display area is represented by the content radiation range corresponding to the display screen. The displayed content can be seen anywhere in this display area. At the same time, according to the attached drawings, it can be known that there is an overlap between the first display area and the second display area, so the overlapping area is marked as the overlapping area. At the same time, it is assumed that the field of view of the person is certain, and the data is existing technology and can be directly obtained.

[0021] S2: Then, the target display screen and its adjacent display screens are obtained, and the target display area, non-target display area and overlap area are obtained. Then, the video surveillance is obtained and its content is identified. According to the content, the number of people corresponding to the display location is obtained, recorded as R, and the number of people corresponding to the target display area, non-target display area and overlap area are obtained, recorded as Rm, Rn and Rc respectively; S3: Obtain the number of people Rc in the overlapped area and obtain the video surveillance in the overlapped area, then analyze and judge the people in the overlapped area according to the video surveillance, and classify them into persons of interest and persons of no interest, and the specific analysis method is as follows: S31: Collecting the information of the person in the video surveillance, establishing a rectangular coordinate system with the person's shoulder as the horizontal coordinate and the head as the vertical coordinate, and then analyzing the person's head movement; S32: When there is a horizontal rotation angle between the person's head and the rectangular coordinate system, determine the direction corresponding to the head. If the direction corresponding to the head is the target display area, then determine whether there is an up-down rotation angle of the head. If so, it means that the person's visual range matches the target display area, and the person is marked as a person of interest. If not, the person is marked as a non-person of interest. If the rotation direction corresponding to the head is not the target display area, the person is marked as a non-person of interest. Based on actual analysis, the display screen at the exhibition location has a certain height. When people need to view the display content, they need to look up to watch. At the same time, the amplitude of the head raising may be large or small. Therefore, when people are located in the overlapping area, it is necessary to combine the corresponding horizontal rotation direction and up and down rotation direction to make a comprehensive judgment on the people.

[0022] S4: Obtain all concerned persons and non-concerned persons, and obtain their corresponding numbers as R1 and R2, and compare the two. When R1≥R2, it means that the number of concerned persons exceeds the number of non-concerned persons, and an adjustment result is generated. On the contrary, when R1<R2, it means that the number of concerned persons does not exceed the number of non-concerned persons, and a result that does not require adjustment is generated. Specifically, by comparing the number of concerned persons and non-concerned persons in the exhibition hall, it is determined whether the target display screen needs to be adjusted accordingly.

[0023] The information adjustment display terminal is used to obtain the transmitted judgment information and analyze the generated adjustment results. By analyzing the current clarity of the target display screen and paying comprehensive attention to the changes in the number of people, reasonable adjustments are made and adjustment information is generated. At the same time, the adjustment information is transmitted to the adjustment information output terminal. The specific method of generating the adjustment information is as follows: P1: Obtain the clarity adjustment standard and the current clarity transmitted by the real-time data acquisition terminal, and then obtain the changes in the number of people being followed within the time period t. When the number of people being followed increases, the increase in the time period t is calculated and recorded as Z. When the number of people being followed decreases, the decrease in the cycle time t is calculated as X. Specifically, the current clarity defaults to high-definition playback.

[0024] P2: Then the increase amount Z and the decrease amount X are obtained, and the two are analyzed to generate corresponding adjustment information, and the specific analysis method is: The specific method for analyzing the increase Z is: Get the current clarity and determine whether it can be further increased. If it cannot be further increased, no processing is performed and the current clarity is maintained. If it can be further increased, substitute the increase Z and the number of people R within the cycle time t into the formula The adjustment value Q is calculated, and then the adjustment value Q is matched with the preset value Qy to determine whether the adjustment value Q is within the specific adjustment interval, and the adjustment information is generated according to the matching result.

[0025] The specific method of analyzing the reduction amount X is similar to the method of analyzing the increase amount, and the adjustment information is generated according to the matching results.

[0026] Combined with actual analysis, there are four levels of clarity adjustment standards: standard definition, high definition, ultra high definition and original picture, and the data processing steps corresponding to the four levels are different. At the same time, the adjustment values ​​Qy corresponding to the four levels are also different. When the calculated adjustment value Q is in the ultra-high definition range, the current clarity is adjusted to ultra-high definition. When the calculated adjustment value Q is in the original picture range, the current clarity is adjusted to the original picture. The above is for situations where adjustment can be made, while for situations where adjustment cannot be made, the current clarity is maintained and playback continues.

[0027] P3: Then, the real-time data transmitted by the real-time data acquisition terminal is obtained, and secondary adjustment analysis is performed on the adjusted target display screen according to the real-time data, and secondary adjustment information is generated at the same time. The specific generation method is as follows: The change of the concerned persons within the time period t1 is obtained. If the number of concerned persons increases, the clarity is not adjusted and normal information is generated. On the contrary, if the number of concerned persons decreases, the change of the concerned persons within the unit time is calculated and recorded as Rb, and compared with the preset value Ry. If Rb≥Ry, it means that the decrease in the number of concerned persons exceeds the preset value and the decrease adjustment information is generated. On the contrary, if Rb<Ry, it means that the decrease in the number of concerned persons does not exceed the preset value and normal information is generated. Specifically, the specific definition of the unit time is based on the actual situation and can be one hour, half an hour or two hours. The specific value is determined by the operator, and the preset value Ry is also set by the operator.

[0028] The adjustment information output terminal is used to obtain the transmitted adjustment information and secondary adjustment information, and display it to the operator through a display device.

[0030] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
